Those antioxidants in rooibos are no joke. They have some very important work to do in the body; that is, seek out free radicals and destroy them.
Free radicals are toxins that are released in our bodies due to exposure to pollution, harmful light, unhealthy foods, and other things. These free radicals interact with molecules in the body, leading to a process called oxidation, and causing oxidative damage — the prerequisite to chronic disease and cancer.
Free radicals directly affect cells in the body, causing mutations and changes in healthy cell DNA. Our best defense against these rascals are antioxidants. Since rooibos tea is chock-full of powerful antioxidants, it can help defend our bodies against cancer.
